TRACTION-EN GINE TENDER.

or other fuel so that the engineer will not have to proceed frequently throughout the day to a point where he can replenish his stock of the supply. a

Another and important object is to provide this trailer or tender with draft appli auces at its rear end by means of which a plow or other machine may be coupledthcrcto and will trail accurately behind the tender although the latter is preferably provided with short. turning gears between its axles.

Details will be found in the following specification, and refcrei'ice is made to the drawings herein and in which:

Figure 1 is a plan view on rather a small scale. showing the traction engine in front and the plow in the rear in dotted lines, and

the draft appliances by means of which this tender is connected with such elements.

Fig. 2 is 'a side'clevation of the tender with its near wheels removed.

Fig. 3 is a plan view of the running gear of the tender with the bolsters and reach in dotted lines, the tongue removed, and the draft bar at the rear turned to one side.

Fig. l is an enlarged perspective detail of said draft-bar and its associated parts.

The traction engine is broadly designatcd by the letter R, and the plow or other implement to be drawn by this tender is broadly designated by the. let-teuP. The axles A of the tender have wheels V journaled at. their extremities as usual, and a tongue T connects the front axle with the engine. bolsters B which support the body of the tender, and no novelty is claimed for the parts thus far described.

15y preference the two axles are connected by short turning gezu',hcrein shown as crossed rods 10, sovthatthey will turn on their king-bolts 11 oppositely and simultane- A reach R rigidly connects two onsly as well understood. Surrounding the forward bolt and disposed between the forward axle and bolster, is a fifth wheel 12 of any approved type, consisting-merely of two washers although this is not essential. Overlying and secured upon the rearward axle is the lower member of another fit'thvheel,

which member consists of a plate 13 a little wider than theaxle and considerably longer than it is wide and through whose center passes the rearward king-bolt. Secured below the rear bolster above this plate is the other-member of said rear fifth wheel, which consists of an upper plate 14 substantially semi-circular on its rear edge as shown, cut away as at 15 at its edge, and provided with a hole 16 at its center mounted on the kingbolt. A brace 17 of strap iron is secured at its center along the lower face of the reach with its forward end bent downward and receiving the lower end of the front king-bolt,

and its rearward end arched downward as at 1S and receiving the lower end of the rear king-bolt, while its rcarmost upturned extremity is secured beneath said upper member of the rear fifth wheel for sustaining and bracing the same.

The d'aft-bar or coupling member by means of which a plow or other trailer P can be connected with this tender, is best seen in detail in Fig. 4:. This consists of a yoke whose stem 20 is perforated as at .21 for attachment to the trailer I, whose upper fork arm 2:2 passes over the upper plate of the fifth wheel and is pivotally mounted on the rear king-bolt, and whose lower fork arm 23 passes beneath the curved edge of said upper member where it is cut away, then turns downward as at 24 and is shaped to pass around the arch of the strap brace, and finally has its lower end mounted pivotally on the lower extremity of the rear king-bolt; and the two fork arms are pierced with alined openings through which may he passed a pin 26 which passes intermediatcly through the hole 16 in the upper plate to lock the draft yoke when it is not desired that it shall swing from side to side. \Vhen the pin is removed, obviously the draft;bar or yoke may swing, although the degree ofits lateral movement is limited by the ends of the cut-awav 'portion in the curved edge of the upper plate, and therefore itmay never swing aside to such an extent as to come in contact with the rear wheels. Thus is provided an extremely powcrtul draft mechanism by means of which the resistance set up by the plow or some other trailer as it is drawn through the earth is conveyed through the running gear and tongue to the tractor and yet has the least possible effect.

nected at two points with the rear king-bolt so as to divide the strain thereon-yet there is no interference with the turning of the rear axle if the short turning gear should be employed as I prefer. The parts are of the desired materials and proportions, and changes in details may be made without dc; parting from the priucipleof the invention.

What I claim as new is:--

1. In a tractor tender having bolsters and axles pivoted thereto by king bolts, the combination with short turning gear connecting theaxlcs, a fifth wheel structure for the rear axle includin a substantially semicircular plate secured eneath its bolster and having a cut out in its rear curved edge, and a strap brace secured beneath this late and downward under this axle; of a raft yoke whose stem has'means for connection with a trailer and whose fork embraces said plate where cut out and the archof the brace, its arms being pivoted on the king bolt.

2. In a tractor tender having bolsters connected by a reach and axles pivoted to the bolsters by king bolts, the combination with short turning gear connecting the axles, a fifth wheel structure for the rear axle in cluding a substantially semi-circular plate secured beneath its bolster, and a strap brace secured beneath the plate and reach and arched downward under this axle; of a draft yoke whose stem has means for'connection with a trailer and whose fork embraces said -plate and the arch of the brace and has its arms pivoted on the king bolt, and a pin for removable insertion through holes in said WILLIAM O.
